The Davis County Sheriff's Office said Thursday that a deputy took a once-missing M-16 rifle before he deployed to Afghanistan.
The deputy faces what the office said could be "administrative action." The matter also will be reviewed by the county attorney, the sheriff's office said in a news release.
The disclosure by the sheriff's office ends the mystery of what happened to the fully automatic M-16, which technically still belongs to the Defense Department. The Pentagon provided 20 such rifles to the Davis County Sheriff's Office in 1998.
